A geothermal central works similarly to a thermic one; the only variation is the way to heat water. Water vapor at high temperatures (up to 600°C) is directed from the inside the earth to the central, allowing the evaporation of water present in different pipes surrounding the boiler. The water vapor reaches higher pressure, thus it is used to move a turbine connected to the generator .When the turbine turns, electricity is produced, which goes from the generator to the transformers. These increase the tension of electricity, to transport this energy along electrical network to home users. The refrigeration system allows to condenses the water vapor, so that can be used again.
